title: New inhibitors of complement fixation.
abstract: A search for compounds that inhibit complement fixation revealed a number of new inhibitors. The presence of EDTA in the phosphate buffer containing complement and compound aided in the detection of compounds that inhibit complement fixation. Compounds were identified as inhibitors that previously could not be shown experimentally to inhibit complement fixation.
